Bug Description

I did a vanilla server install of 2018.4LTS (ie. accepted all the defaults for a server) and am now attempting to faithfully follow the instructions here:
 https://help.ubuntu.com/lts/serverguide/sssd-ad.html.en

Straight off the bat the guide is making assumptions that are not valid for a default install.

Item 4 says "The domain controller is the primary DNS resolver as specified in /etc/resolv.conf"

However my resolv.conf says that the nameserver is 127.0.0.53. I have NFI what this address means because I certainly haven't set this as an IP address for anything. Comments in the top of resolv.conf suggest that systemd is somehow behind all this.

I have no idea if this is a problem, or is systemd wrong, or is the documentation wrong.
